There will be changes to public transport timetables over the next few days due to the Easter holiday, the Athens Urban Transport Organization (OASA) said on Wednesday. On Saturday, Sunday and Monday, buses and trolley buses will mostly follow their normal Sunday schedules. On Easter Saturday, the service will wind down from 10 p.m. The express buses to the airport will operate as usual. On Friday and Saturday, the timetable for the metro, Kifissia-Piraeus electric railway (ISAP) and tram services will not be extended to 2 a.m. as is usually the case on weekends. Services during the day will also be less frequent than usual. Passengers can obtain more information by calling 185 or logging on to www.oasa.gr.
